摘要
将水产养殖与农业种植相结合(稻渔综合种养)是提高农产品产量、推动农业绿色发展的重要途径.然而,稻渔综合种养对多营养级土壤生物多样性和多重功能的影响仍然未知.通过对中国19个地区(~1300 km跨度)的131个农田(包含水稻单作和稻虾综合种养)进行野外调查发现,与水稻单作相比,稻虾综合种养导致土壤多营养级生物多样性(如真菌vs.无脊椎动物)和生态系统多重服务功能(如支持vs.调节服务)的权衡.本研究为综合评估稻虾综合种养的经济和环境效益提供了新的见解,呼吁在区域范围内合理布局水稻单作和稻虾综合种养面积以优化农田多重生态系统服务功能.
Global food security is challenged by climate change,population expansion,and resource constraints[1].Integrated farming has been proposed as a sustainable approach to boost food production by taking advantage of the synergetic interactions among contrasting edible plant and animal species[2,3].A relevant example is the combination of aquatic animals such as crayfish,carp,and crab with rice farming,to increase the provisioning ecosystem services delivered by agrosystems[3].
